  1. 1. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Gustavsson; [2021]
    Keywords : Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Abstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE

  3. 2. Fertiliser derived from human urine : novel media for alkaline urine dehydration

    University essay from SLU/Dept. of Energy and Technology

    Author : Christopher Friedrich; [2021]
    Keywords : nutrient recovery; fertiliser; urine drying; source separation; magnesium oxide; calcium hydroxide;

    Abstract : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. READ MORE

  4. 3. Kan behandling med kanagliflozin sänka postprandiella glukos- och insulinkoncentrationer hos hästar med EMS? : utvärdering av behandlingseffekten med hjälp av ett oralt sockerbelastningstest

    University essay from SLU/Dept. of Clinical Sciences

    Author : Olga Svensson; [2020]
    Keywords : häst; ekvint metabolt syndrom; EMS; insulinresistens; hyperinsulinemi; kanagliflozin; oralt sockerbelastningstest;

    Abstract : Ekvint metabolt syndrom (EMS) är en endokrin rubbning hos häst som leder till ökad risk för utveckling av fång. Syndromet innefattar insulindysreglering, basal- och postprandiell hyper-insulinemi, insulinresistens, samt övervikt och/eller regionala fettdepåer. READ MORE

  5. 4. Human Urine : can it be applied as fertilizer in agricultural systems?

    University essay from Högskolan Kristianstad/Fakulteten för naturvetenskap

    Author : Julia Filling; [2018]
    Keywords : Ecosan; source separation; non-diluted urine; aurin; urine powder; organic fertilizers;

    Abstract : In cities today, vast amounts of nutrients are being wasted. Improvement in nutrient management within agriculture can contribute to a more sustainable society. Reusing nutrients in agriculture could aid in creating a more circular system, where organic fertilizers can be used instead of chemical fertilizers. READ MORE

  6. 5. Challenges during start-up of urine nitrification in an MBBR

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ellen Ascard Edefell; [2017]
    Keywords : Urine; source-separation; urine stabilisation; nitrogen recovery; nitrification; moving bed biofilm reactor; MBBR; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Abstract : Nitrogen and phosphorous compounds are secreted by humans and treated in wastewater treatments plants. These substances are also found in agricultural fertilisers and needed for plant growth. Nutrient recycling is limited in conventional treatment systems and valuable products are lost. READ MORE
